You can now fine tune your ride height more acuratly when .5 or even 1mm increments just will no do. Or more to the point when you want to copy the pro’s setups!!!

Check them out Here and specs below…

• chassis ride height gauge for 1/10 nitro and electric touring cars
• allows ultra-fine and very precise adjustment of front/rear ride height
• ride height range (3.8-8.0mm) within most frequently used ride height settings
• super-precise increments of 0.2mm in the most frequently-used range (standard ride height gauges typically use 1.0mm increments)
• CNC-machined, high-quality lightweight duraluminum
• elox-coating for smooth, long-lasting finish
• fine-engraved HUDY logo and scale
• scale engraved on top of steps for easy viewing and use
• most precise ride height gauge on the market
• a “must have” for professional racers

We have reduced the price of our Demon DL3600 to just £34.99 . Why? In all honesty because they are not selling as quick as our other packs. We have no idea why as these are exceptional value for money especially being rated at 25C too. They are also BRCA approved for any race meetings. So grab a bargain HERE

Read HERE about the Xray Equalized Corner Speed (ECS) drive system. Well I’am impressed anyway.

Our latest Demon LiPo packs have finally arrived.

Some of you have asked for the option of the Demon LiPo to be fitted with Corally style tube connectors built into the pack.
We aticipate delivery any day if this is more to your liking.
Same extreme high quality, high C rating with ultra low resistance like all of our LiPos.
Also with the same low prices and sorry, but no fancy packaging.
For those that do require fancy packaging and wish to throw it in the dustbin 10 seconds later, then this can be purchased for an additional £8 .

Mardave Stock has arrived.

We can also ship the famous british Mardave brand abroad now.

Team V-Dezign is releasing new 1-piece top decks for TRF 416 and Serpent S400 touring cars.

The V-Dezign TRF416 deck fits the car perfectly and gives more flex to the car in rear. Also less tweak issues as there are no separated topdeck parts like in standard 416 has. Made from 2mm graphite.

The Serpent S400 top deck is a long waited option for S400 users.
Team Serpent fatory team drivers are using these decks also! Compared to standard topdeck, the V-Dezign long 1-piece deck gives more general traction and more on-power steering. Made from 2mm graphite. Also allows use of LiPo packs like the like Team Drivers!

We have been doing a lot of testing since LiPo battery packs have been released for RC cars.

Comparing different packs, different C rated packs and other attributes, We have rejected a number of cells from different manufactures due to inconsistent balanced cells within the packs and and also by internal resistance.

The C rating is all well and good but how do you know if a high rated (e.g. 30C) rated pack is actually what is says on the packet.

We have tested LiPo of various C rating from different manufacturers and the differences really are amazing. Both on the track and by measuring internal resistance.

Normal NiCd and NiMh cells are very different to LiPo packs but one thing that remains a very good measure of a good battery is the internal resistance.
The lower the resistance the better the pack in terms of performance. The lower the resistance is the best indication of the C rating also.
The lower the rating,  the higher the C rating.
The Demon DL4000 packs for example are rated at 30C(120 amp continuous) have an internal resistance of 3mOhm typical.
The Demon DL5000 which are rated at 20C (100 amp continuous) have 3 to 4mOhm
The Demon DL3600 which are rated at 25 C (90 amps continuous) have 4 mOhm.
We recently tested some 3800 packs from another manufacturer rated at 25C+ and they only gave 9mOhm internal. i.e. more than double the resistance.
Other manufacturers packs have shown figures of 12 mOhms or more.
Replacing these with a new low internal resistance LiPo pack of cells will transform a car in terms of speed and punch.

Note also that the power and capacity and long life of a LiPo is directly proportional to the weight, so there is no way a lightweight LiPo will deliver very high power for the full duration without fading and losing performance after fewer charges.
A high quality heavy LiPo will remain consistent and we have charged a DL5000 300 times without any loss of power.

Note that good quality LiPo cells also do not lose duration at different rates like NiMh cells. Therefore a quality LiPo will retain balance within the cells in the pack even after 100s of charges.

The balance connector is a means of testing a LiPo occasionally to give peace of mind and just to make sure all is ok. It is not necessary to charge with the balance lead every time, and we have charged Lipo packs 100s of times without the balance lead without any problem. Also that the pack will charge faster without the balance lead as the charger does not have to keep checking each cell.

No Cells or Animals where blown up in this testing. Thanks for listening.

Thanks

Oh well, another one of those weekends and off to Bashley for some boat racing. I mean Car racing if it is dry!. This time the Gazebo is water proof…. We think

New Cyclone car, New Nosram 10.5 motor, New Futabe Servo, New 2.4ghz KO Esprit III system. What else can I change? Maybe the the driver if it all goes wrong.

We were not going to use our blog as a advertising point but thought I would for this, as loads of you have been asking when the Serpent S400 gear diffs would be back in stock. Guess what, they are. Finally. Thanks.
